<p>I reported the first of my two ACT test dates as 12/2012 instead of 12/2010. I just now noticed this error (a few weeks after submitting the applications). I actually didn't send the official score report from this date to any schools and only reported one component score from it on the Common App.
Should I email the colleges I've applied to and notify them of the mistake? Or is it insignificant, especially considering none of them have the official report?</p>
